LOUIS J. KREUTZBERG, OF EASTON, PENNSYLVANIA.

MOLDING-FLASK.

To all whom it may concern:

Be it known that I, LoUIs J. KREUTZBERG,

I a citizen of the United States, and a resident of Easton, in the county of Northampton and State of Pennsylvania, have made certain new and useful Improvements in Molding-Flasks, of which the following is a specification.

My invention relates to improvements in molding flasks and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide a flask made up of a number of copes, said copes being fastened together so as to form practically a unitary cope with means for fastening the cope thus made to the drag.

A further object of myinvention is to provide a novel form of fastening means so that the several parts of the flask may be quickly clamped together, or unclamped, as occasion demands.

A further object of my invention is to provide a series of lugs which are permanently attached to the copes, and drags, of the molding flasks, and which are designed to receive handles for lifting these parts or for transporting them.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a perspective view of a molding flask constructed according to my invention. Fig. 2 is a section through a por tion of the device showing the means of fastening the parts together; Fig. 3 is a side view of a portion of a cope showing a handle secured in place between the lugs; and Fig. 4 is a perspective view of a handle.

Referring now particularly to Fig. 1, I have shown therein a flask comprising a bot tom portion or drag 1, and two superimposed copes 2 and 3 respectively. The end of the drag and of the copes is provided with the usual guide plates such as those shown at Specification of Letters Patent.

Application filed March 13, 1911.

Patented Sept. 5, 1911. Serial No. 613,976.

1 2 and 3-, having perforations such as that shown at 3 arranged to receive the pins such as that shown at 1 and 2 in the brackets 4: and 5 respectively.

On the sides of the drags and the copes, at the ends thereof, I arrange the lugs 6 and 6 These lugs as will be seen from Fig. 2, are curved on one side and have faces on the opposite side which incline toward one another as clearly shown in Fig. 2.

At 8 are shown clamps which are arranged to engage adjacent lugs on contiguous portions of the flask. In Fig. 1 these clamps hold the copes together and also unite the copes with the drag. The clamps are tapered slightly from one end to the other so that when they are pushed into place they securely hold the parts together. The lugs may also be tapered as shown in Fig. 3.

In Fig. 3 I have shown the two lugs 6 and 6 as forming a socket for the handle H. The latter is provided with an end it having faces 7b which corresponds with the inclined faces 7 of the lugs.

From the foregoing description of the various parts, the operation thereof may be readily understood. In assembling the flask the handles H may be thrust between adjacent lugs of a part of the flask, such as the cope, in the manner shown in Fig. 3, and this part may be then lifted and placed upon the drag, the guide pin 1 entering the guide plate 1*. The guide pin 1 may be threaded and may be secured to the guide plate 1 by means of a nut 9. The other sections of the cope may be handled the same way. The clamps are now put on and it will be noticed that they engage the lugs of adjacent sections of the flask. They may be driven in place, thereby securing all the parts securely together.

The provision of the lugs affords means for the use of long handles where cranes are lacking, these handles being capable of instant removal as soon as the flask is in place. It will be understood that the lugs may be attached to flasks of wood, iron or steel.

I claim In a molders flask, a plurality of separate parts, a pair of lugs carried by each part near the end thereof, said pair of lugs being provided With adjacent inclined faces, and said lugs being disposed at an angle to one another, the outer ends of each pair of lugs being farther apart than their inner ends to L. P. APPLE.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. C.
